"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"Strong Builders did our screened in porch. Working with Jack was fantastic. As one of his previous review's states "renewed my faith in contractors" is absolutely true. He was punctual, had great communication, was clear and up-front about everything. His experience reflected in his work. He is meticulous but efficient. He clearly takes pride in his work. Probably the most bind-boggling thing is that he does the vast majority of the work himself and by himself. He knows the building codes in and out, which made getting permits approved as smooth as it gets in a county that is notorious for being difficult to build in. Jack refused to cut corners and confidently stands behind his work. We will absolutely hire him again and cannot recommend him more."

"Jason and his team did a fantastic job on an external stairwell for our property. It is now the nicest part of our house! Jason is personable and professional. Communication was easy throughout. Jason works as an inspector in his home town, which made me feel very comfortable that his work would be to code. He gave us a fair quote and not only stuck to this, but also adjusted the price downward when he did not use some materials that he anticipated needing initially. I will certainly be using Jason's services in the future if needed and would highly recommend Mason Sky."

"Highly recommended. Jose and Cesar were great. They were reliable and their work was excellent. They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

"My house needed to be repaired from a huge fire. I was looking for a GC that has extensive knowledge of fire damage. After multiple quotes, I chose WS Builders because the owner was very professional and knew what he was talking about. Wladimir assisted me from beginning to end. We gutted the whole house and replace all the electricity. This was a big project and it was necessary to find a GC who had previous experience in rebuilding a house damaged by fire. I am very please with Wladimir's work ethic and professionalism. He had a quick turnaround and communicated thoroughly to ensure that I fully understand what was going on during the project. I recommend using him if you are looking for somebody with years of experience. Regardless of what job it is, he has the subcontractors to ensure the job is completed in a timely manner."

"William and his crew did a good job of the laborious and complex task of removing and replacing a rotting, out of date, porch structure on my home. William walked me through every step of the way and maintained great communication throughout the project letting me know where they were in the project as well as any difficulties or complexities that they faced. William stood behind his work addressing any and all concerns I had when the job was finished. I never felt abandoned or isolated at any point of the project. I felt more included in this project than at any time while working with different contractors. Overall, I highly recommend William. He proven himself to me as someone who is not only capable but someone is motivated and passionate in completing and renovating homes or structures. I will be using William and his crew in the future. I know for a fact I have gained a vital resource for any more work needed to be done in my home."

FAQs for addition to existing structure building service projects in Southborough, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
